SOLE-MACHINE.

Patented July 2, 1912.

Application filed April 30, 1908, Serial No. 430,115. Renewed october 5,1911. Serial No. 652,984.

To all whom it may concern Be it known that I, Emsrus E. VINK- LEY,citizen of the United States, residing at Lynn, in the county of Essexand State of Massachusetts, have invented certain new and usefulImprovements in Sole-Machines; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the artto which it appertains to make andusethesame.

The invention relates to machines for operating upon a sole or insoleblank which has been partially prepared for use by channeling or byother operations resulting in the formation of a marginal abutment onthe blank, 'and is intended more-particularly as an improvement upon thelip turning machine shown and described in Patent No. 635,772, grantedto J. B. Hadaway October 31, 1899, and upon the lip turning machineillustrated and described in my application filed May 24, 1906, SerialNo. 818,53 although the invention is not confined in its application tothe lip turniiu machines shown in said patent apd application, and maybe embodied in other forms of machines designed to perform otheroperations upon the margin of a sole.

In my application above referred to I have shown and described a lipturning machine such as is shown in the above patent to Hadaway,provided with a guide arranged to engage a channel or other marginalabutment on the blank in opposition to the devices operating upon themarginal portion of the blank, and to cooperate with the feeding devicesto automatically guide the blank and swing it at proper times inconformity wlth the curvature of the edge at the point where the marginis being op-' erated upon. In removing and inserting the workin themachine constructed as shown in the above application, the operator mustnot only depress the Work support in the usual manner, but inust alsomanipulate the abutment engaging guide in order that the work may beproperly removed, or maybe properly ositloned with relation to the lipturning e'ices in inserting the Work. In order that the guide may bethus manipulated by the operator the guide is mounted to swing into andout of position to eiwa e the channel or other abutment, and is heldyieldingly in position to engage the chem:

-.ness of the soles, or to inequalities uel. With the guide thusmounted, it tends to return to normal position Whenever moved from suchposition by engagement with the work as it is inserted or removed, andinterferes more or less with the convenient positioning of the sole inthe machine andthe removal of the finished sole therefrom.

It is the primary object of the present invention to overcome thisobjection to the prior construction and arrangement of the guide, and toso arrange and operate the guide that it will not interfere with themanipulation of the work by the operator in either removing or insertingit in the machine, thus enabling successive soles to be presented to thedevices for operating upon them with convenience and rapidity. I To thisend the primary feature of the invention contemplates the provision ofcon nected means for retracting the guide and work support, so that inretracting the work v support the operator also retracts the guide.

The invention also contemplates the provision of means for automaticallyreturning the guide into position in the channel when the work supportis returned to position to support the sole durin the operation of thlip turning devices t1ereon. The specific construction and arrangementof the connections by which the guide is retracted upon the retractionof the work support, and is automatically returned to active positionupon the return of the work support, is not material to the invention inits broader aspects, but may be varied without departing from theinvention. It is usual, however, in this class of machine, to retractthe work support by means of a treadle, and in accordance with a furtherfeature of the invention, the guide and work tions With an actuatingdevice such as a' 'treadlc, so arranged that upon operation of thedevice, both the guide and Work support will be retracted, and uponrelease of the device the guide and work support will be returned intoposition to engage the channel or other abutment, and to support thework. These connections are also so arranged that the position of theguide will be independent of any variations in the position of the worksupport due to variations in the thickin different par-ts of a sole.

The various features of the invention will be understood from aninspection of the accompanying drawings, in which Figure 1 is a sideelevation partly in section of a lip turning machine embodying theinvention in its preferred form; Fig. 2 is once may be had for a fullunderstanding and setting OCCll P.- v

-tion by means of a of the construction and mode of operation of theparts which are not hereinafter ex plained.

As shown in the drawings, the machine is provided vwith a work support1, a feed wheel 2, a lip turner 3, a lip setter'et, and a presscr foot5, all of which are constructed and operated in the manner set forth inthe patent above referred to. The machine is also provided with a guide6 arranged to engage the channel of the insole adjacent and opposite tothe point at which the lip turning and setting devices are operating,and serving to maintain the blank in proper position relative to thedevices which operate upon it as the blank is fed. This guide isarranged at oneside in the direct-ion of feed of the point of operationof the feeding devices upon the sole,'so that it cooperates with theabutment formed by the bottom of the channel to swing the sole whenever,owing'to the curvatureof its edge, it tends to swing away from properengagement with the lip turning devices, and thus cotiperates with thefeedingdevices to automatically control the feeding movements of thesole, and to insure the presenting of the edge of the solo in properposition to the lip turning devices throughout their opera tion upon thesole, and without requiring that the sole be swung by: the operator inrounding the toe, or at other points where an abrupt change intheout-line of the sole The guide 6 is mounted for longitudinaladjustment in the end of a rock shaft 7 The end of the rock shaft 7'Lhroughwhich the guide 6 slides is split, as indicated in Fig. 3, andthe guide is clamped in adjusted posiscrew 8 which draws the two partsof the. split end of the shaft together. The rock shaft 7 is mounted inthe end of a lever 9, and the guide is held yieldingly in position by acoiled spring 10 which holds the outer end of the guide against anadjusting screw .11. By turning the screw 11, the channel engagingend-of the guide draws the uide 6 ness of sole being operated upon, andby movingthe guide longitudinally in the rock shaft, the guide may beadjusted to properly engage the channel. The rear end of the lever 9 ispivotally connected to the upper end of a rod 12 which extends downthrough the base plate 13, and is connected by means of a link 14 with asuitable operating device such as a treadle (not shown).

The guide 6 is held in position in the channel by means of a spring 15,surrounding the rod 12 and interposed between the plate 13 and a collar16 secured to the rod. The upward movement of the rod 12, under theinfluence of the spring 15, is determined by a nut 17, threaded on therod 12, and arranged to engage the under side of the plate 13. Byadjusting the nut 17, the position of the guide 6 may be varied. Thespring 15 acts to yieldingly maintain the guide 6 in engagement with thechannel or other abutment, and also acts to automatically advance theguide into engagement with the channel after it has been retracted bythe depression of the rod 12. The dc? award movement of the rod12, whichwithdraws the guide 6 from the channel so that it will not interferewith the removal or insertion of the work, also effects the withdrawalof the work support- 1 so that the finished sole may be removed and anewsolo brought into proper relation to the lip turning devices. Theconnections for effecting this movement of the work support comprise alever 18 which is pivotally connected at 19 with the lower end of therod 20, the upper end of which is connected with the work support. Therear end of the lever 18 is arranged to underlie a nut 21, threaded onthe rod 12, so that it maybe adjusted to properly engage the end of thelever 18. The work supportis held yieldingly in its upper position bythe spring 22, the position of the work support being determined by theadjustable nuts 23, one of which is arranged to engage the end of thesleeve 24, which supports the lower end of the spring 22. With the partsthus connected, an operation of the treadle or other device connectedwith the link 14 in a direction to move the rod 12 downward, retractsthe work support 1 and also withfrom position to engage the channel orother abutment so that the guide in no wise interferes withthe removalor insertion of the work. After the work has been insertedin the usualmanner, and the treadle or other device through which the rod 12 isoperated is released, the guide 6 is automatically advanced intoengagement with the channel by the action of the spring 15, while thework support 1 is automatically forced against the under surface of thesole by the action of the spring 22. The position of the guide 6 isdetermined by the position of the nut 17 and is unaffected by anymovement of the work support 1, which may position itself against theunder surface of the work Without effecting any movement in the rod'12,'since the lever 18 is free to,

move downward away from the nut 21 on with such a guide,,it will beunderstood that it is not essential to the invention in its broaderaspects that the guide should engage a channel, and that-its r-m maybemodified to cooperate with other forms of .abutments,v1ch, for instance,as grooves or shoulders, hich are sometimes used in place of a channel,to receive the seam. It will also be understood that the invention maybe embodied in machines for perform- .ing operations other than that-ofturning up and setting the lip, so far as the broader features ottheinvention are concerned.
